我已经编写了一个代码来将csv文件中的数据加载到postgresql表中。代码运行得更早，突然出现了错误 py4j.protocol.Py4JJavaError: An error occurred while calling o65.save. : java.util.ServiceConfigurationError: org.apache.spark.sql.sources.DataSourceRegister: Provider org.apache.spark.sql.kafka010.KafkaSourceProvider could not be instantiated 在连接jdbc驱动程序时似乎出现了问题。任何建议都会有帮助，

import pyspark
from pyspark.sql import SparkSession, Row

sc = pyspark.SparkContext('local[*]')
SqlContext = pyspark.SQLContext(sc)
spark = SparkSession(sc)

productsFF = sc.textFile("C:\Hadoop\Data\ProductType.csv")
productsDF = productsFF.map(lambda p: Row(product_type_intrnl_id = int(p.split(",")[0]), 
product_type_code = p.split(",")[1], product_sub_type_code = p.split(",")[3])).toDF()

productsDF.createTempView("product_type_tmp")
product_type_tmp = SqlContext.sql("select * from product_type_tmp") #.show()

SqlContext.sql("show tables").show()

product_type_tmp.write.format('jdbc') \
    .option("url", "jdbc:postgresql://localhost:5432/xxxx") \
    .option("dbtable", "xxxx") \
    .option("user", "xxxx") \
    .option("password", "xxxx") \
    .option("driver", "org.postgresql.Driver").mode("append").save()

下面是详细的错误，

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
